This invention relates 'to machines for drying' hosiery and other knitted articles, and it has for aprimary object the provision of a machine including a continuous guideway over which detached form carriers are traversed in intimate proximity while in the drying enclosure, but spaced apart when exterior thereto forV clothing and'stripping. Another object is to provide a machine of Vthe `above typified form characterized by automatically actuated ingress andy egress closure instrumentalities', whereby increased efficiency and economy are attained.- Other objects and attendant advantages inhering to this invention will be later on referred to or particularized,fand said invention-may be tersely expressed as concombinations and arrangements of parts hereinafter fully described, and thereafter succinctly defined bythe appended claims. In the furtherl disclosure ofthe invention reference is to be had to the accompanying .sheets of 'explanatory drawings, constituting a part'f this specification, and in arts are distinguished by the same indices t roughout the several vlews.

Accordingto the embodiment of my inform 1224. semi No. 712,966.

vention illustrated I construct a rectangular framework of standard section verticale 10, braced b similar section horizontale 11, and close in by thermo-insulated plates to provide an enclosure 12 in spaced relation to the floor level 13. This enclosure 12 '1s 1provided with a. roof 14 having an inverte frusto-pyramidal port-ion or deflector 15, for a purpose hereafter explained; 'and a bottom 16 having a guideway therein constituted by parallel slots 17, 17 connected by a rear arcuate course 18; and said parallel slots communicate, at the front of the machine, with vertical openings 19, 20,-Fig. I-In the enclosure wall 21, res ectively affording ingress and egress for t e forms 22, as latter on fully set forth.

sure 12, and supported by standard section verticals 2 3, in spaced relation to the bottom16,-is a rectangulaacondiiit24gonyentional-ly.v housingr a plurality-.f radatprs 25, throughwhich heating-,liiedinmscifoulated -in accor-dance with prevailing practice. Approprate'ly secured to :opposed verticals 23 in theupper part of the conduit 24 is a housing 26 for the horizontally rotatable fan 27; the shaft 28 whereof is journaled in a bearing 29. supported concentrically within the frusto-pyramidal deflector 15, aforesaid. Rotary motion is imparted to the vfan 27 through the medium of f'miter couple 30, driven by a horizontal counter- Conveniently mounted within the encloshaft 3l, journaled in bearings 32, secured of the enclosure 12'; andV aoed with respect 15 ensures effective diffusion of the dryini medium with'a looped directional flow as clearly indicated by the arrows on Fig. III.

Referring to the `forms 22, each of which is removably supported by al1-.individual carrier shoe 35 of sexangled configuration in plan with opstanding flanges 36, between lun lua

which the said forms are securely clamped,

in any of the well known ways. Furthermore, the u standing flanges 36 are fitted with opposed angle sections 37, the lateral portions whereof are adapted to snugly t transversely across the slots17, 17 aforesaid, whereby the latter are closed-in against .wasteful escape of the heating medium, as

will be appreciated 4by an examination of Figs. II and III, more particularly. Still rected co-planal angle trance and exit portions 41, 41', extend- -ing rearwal'ds from the front of the enclosure 12, in parallel relation below the bottom 16, with a connecting arcuate back end 42; and said trackway is disposed co-planal with a platform 43, having a rectangular slot 44 therein, and an upstanding frontal flange 45 affording Vguidance for the carrier shoes during progression exterior of the enclosure 12. It is, however, to be'remarked that .the rectangular slot 44 is co-extensive with, and constitutes a part of the course traversed by the carrier shoe pins or studs 38. In connection with the platform 43, there is fitted a rectangularly congured sheet metal embossment 46, the shorter ends Ywhereof align with the inner vertical flanges of the trackway 39, as clearly `shown in FiIgI. II.v f Y aving set forth the structural characteristics of the drying enclosure 12 and the detached form carrier shoes 35, I will now describe the mechanism effective to progress the series of forms 22 through the corridor 34, in abutting relation, as well as'traversing-thesame relatively spaced apart while a outside the enclosure 12, for stripping and n, clothing. The said mechani-sm is operated through the medium of a coned pulley 47.0n'

the countershaft 31, and beltI transmission 48, adaptedto drive a reversely stepped pulley 49 secured on a short shaft `50, Journaled in bearings 51 mounted in the machine subframework. Secured on, or integral with,

"the shaft 51 `is a wormu52 in gear with -a worm wheel 53, splined to a horizontal shaft 54 journaled in bearings 55, mounted on angle` section cross-braces 56 in .the machine sub-structure. This horizontal shaft 54 is fitted at its front end with a crank arm 57, in turn connected by a pitman 58 vto a vertically movable lever arm 59, fulcrumed at its lower end to a pivot block 60, rigidly .supported by the machine framework. Pivotally connected to the upper end of the lever arm 59,'is a link 61, in turn similarly couneoaaai pled to a slide bar or shifter 62, adapted for longitudinal reciprocation relative to a suitable guide 63, as later on fully described. The guide 63 is conveniently a standard angle-sectlon rigidly secured across the front of the machine framework in juxtaposed relation below the platform 43, with its vertical limb slotted at 64 to receive lateral studs 65, 66 on the shifter 62, .the former of which also serves as a pivot for the upper end of the link 61, as best shown by Fig. I. Pi'votedby studs 67 to the rear face of the shifter 62, are a pair of pawling members 68, provided with lateral arcuately-curved teeth 69, adapted vto cooperate with the carrier shoe pins or studs 38, to effect exterior progression of successive forms 22, in the manner hereafter set forth; and said pawl- 111g members 68 are prevented from oscillation, otherwise than as lateron explained, by stops 70, provided for the purpose on the back face of the shifter 62.

Simultaneously co-operative with the means just explained is a triple-acting pusher mechanism now to be described. This mechanism includes a double-ended horizontally movable lever arm 71, fulcrumed by a stubshaft 72 in bearings 73, 74 the former '7 3 of which is rigidly secured to the underside of the embossment 46 hereinbefore referred to, whereas the latter 74 is firmly attached to one of the verticals 10; and a second relatively longer lever arm 75 similarly pivoted by an appropriate bearing 76 fixed to the bottom 16 of the enclosure 12. These lever arms 7l, 7 5 are co-ordinated by a multiplying linkage 7,7, 78 so that the throw of the latter lever arm, 75, is relatively greater than that of the former, 71, for a purpose later on explained; and each lever is fitted at vits outer end with a spring influenced finger 7 9. Oscillation of the triple-acting pusher mechanism is effected by means of a forked tappet member 80, attached on the stub shaft 72, being disposed' in the path of movement of a vertical pin. or projection, 81, on the end of the pitman 58, where it is pivoted at 82 to the vertically movable lever arm 59, as best shown in Figs. I and IX.

Associated with, and simultaneously actuated by, the triple-acting pusher mechanism 71, 75 is a means for automatically openingand closing sliding doors 83, 84 to permit ingress and egress of the forms 22,

lUU

through the openings 19, 20 relative to the l drying corridor 34. These doors 83, 84, as best shown in Figs. I, IV and V, are susjpended in the well known way by antifriction rollers 85 adapted to traverse the hanger track 86, eachsaid door being operated'by means of a. quick-action compound or translating leverage 87, 88; the-latter member 88 being fulcrumed at 89 to the machine framework, and provided with a crank arm 90. Appropriately attached to the free end'of the crank arm 90 is a universal connection 91, in turn hinged to a rock member 92, fulcrumed at 93 Vto the platform 43, and having a downwardly inclined cam face 94 with which the aforesaid dou-` ble-ended lever arm 71 operatively engages, and is adapted to swing the rock member 92 upwardly to effect opening of the doors 83, 84. These doors 83, 84 are adapted to gravitate back to closed position in the well known way.

Having detailed the several coordinated mechanisms incorporated in my novel automatic drying machine for hosiery and other knitted articles, the operation thereof may be brieiy summarized as follows:

Assuming the machine is designed for drying hosiery and that clockwise' motion 1 s 1mparted thereto by the belt drive 33, 1t will be obvious that the crank arm 57 will be constant-ly rotated by the worm drive 52, 53 in a counter-clockwise direction thereby swinging the lever arm 59 with a to-and-f ro motion in a vertical plane, and intermitf tently reciprocating the slide bar or shifter 62 from the right to the left-hand with respect to Fig. I, and vice versa. Now it will be readily apparent from the preceding de# scriptive matter` relating thereto, that reciprocation of the slide bar or shifter 62 will effect horizontal oscillation of the triple-acting lever arms 71, 75. Now, let it be assumed that said lever arms 71, 75 occupy the respective positions shown in Figs. II and IX, rocking of the lever arm 59 to the left-hand will yadvance the pin 81 into engagement with the bifurcated tappet member 80 and partially turn' the stub shaft '72 about its aXis whereby the double-ended lever arm 71 will withdraw a form carrier 35 from the corridor 34 to the position designated a-Fig. II-in the platform rectangular slot, whereat the stripper operative is stationed to remove the dried article. Concurrently therewith, the form carrier 35 at the position designated Z), whereat the "boarder operative is stationed to reclothe successive forms .22 Vwith wet articles. will be advanced into thcdrying corridor 34, and simultaneously1 stripped form carriers located at c anda, will-be progressed by the pawling members 68 to the positionsv denoted as Z) and c respectively.' Now it will be .perfectly obvious thatthe sliding doors 83` 84 will have been automatically opened to permit the egress and ingress form carves rier progressions just described. and it is pointed out purely by wayiof clarifying such operations that if' the dwell period of time intervening each progressive movement of successive form carriers 35 be,y assumed as fifteen seconds, the door actuating mechanism can be designed so that the doors 83, 84 only remain open for three seconds so that escape of the drying medium from the corridor 34 is purely negligible. Furtherexplained a, form carrier 35 will have been progressed over the arcuate end 42' of the trackway 39, from the entrance side 41, to the exit side 41', by means of the lever arm 75. Obviously movement of the slide bar or shifter 62 on the return stroke or towards the right hand in Figs. I and II will result in a reverse motion, being imparted to the lever arms 71, 75, which, by virtue oftheir spring iniiuenced finger ends 79, willrelease the respective form carriers 35 advanced as above described, and said arms will be returned to rte-operative position as will be readily understood by anyone in the least acquainted 4with the art. Particular attention, however, is directed to the fact. that the several form carriers 35 are progressed along theentrance and exit sides 41, 41 of the traclrway 39 in intimate. contact, whereas they are advanced over the platform 43 relatively spaced apart.

`From the foregoing description it is thought that the progressive course of the form carriers 35, will be fully understood Without further explanation, while the attendant economic advantages inhering to my novel drying machine are so apparent not to necessitate specific tabulation. Finally, the assemblage illustrated and explained in detail, is not to beconservativelv construed, as numerous changes' and modifications in the general aggroupment of parts will naturally suggest themselves in accommodatingthe :machine for drying'dif- .ferent articles; therefore, the right is reserved to make all such reasonable var1a-v tions that fairly lie within the scope of the subioined claims.
